Safety Standards.
Y Only qualified persons should install, operate, maintain, and
repair this unit.
Y During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts touching the
welding wire are electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
D Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
D Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
D When making input connections, attach proper grounding conduc-
tor first – double-check connections.
D Frequently inspect input power cord for damage or bare wiring –
replace cord immediately if damaged – bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not drape cables over your body.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable.
D Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
D Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
D Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breath-
ing air is safe.
D Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
OM-1500–2 Page 2
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
ARC RAYS can burn eyes and skin.
D Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant mate-
rial (leather and wool) and foot protection.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
WELDING can cause fire or explosion.
D Protect yourself and others from flying sparks and hot metal.
D Do not weld where flying sparks can strike flammable material.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
D Do not use welder to thaw frozen pipes.
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
HOT PARTS can cause severe burns.
D Do not touch hot parts bare handed.
D Allow cooling period before working on gun or
torch.
MAGNETIC FIELDS can affect pacemakers.
D Pacemaker wearers keep away.
D Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Wear approved ear protection if noise level is
high.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
CYLINDERS can explode if damaged.
D Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.
D Never weld on a pressurized cylinder – explosion will result.
D Use only correct shielding gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and
associated parts in good condition.
D Turn face away from valve outlet when opening cylinder valve.
D Keep protective cap in place over valve except when cylinder is in

1-5. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electro-
magnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to power-
frequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as possi-
ble.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

1-5. Information sur les champs électromagnétiques
Données sur le soudage électrique et sur les effets, pour l’organisme,
des champs magnétiques basse fréquence
Le courant de soudage, pendant son passage dans les câbles de sou-
dage, causera des champs électromagnétiques. Il y a eu et il y a encore
un certain souci à propos de tels champs. Cependant, après avoir ex-
aminé plus de 500 études qui ont été faites pendant une période de
recherche de 17 ans, un comité spécial ruban bleu du National Re-
search Council a conclu: “L’accumulation de preuves, suivant le
jugement du comité, n’a pas démontré que l’exposition aux champs
magnétiques et champs électriques à haute fréquence représente un
risque à la santé humaine”. Toutefois, des études sont toujours en cours
et les preuves continuent à être examinées. En attendant que les con-
clusions finales de la recherche soient établies, il vous serait
souhaitable de réduire votre exposition aux champs électromagnéti-
ques pendant le soudage ou le coupage.
Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1 Garder les câbles ensembles en les torsadant ou en les
attachant avec du ruban adhésif.
2 Mettre tous les câbles du côté opposé de l’opérateur.
3 Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4 Garder le poste de soudage et les câbles le plus loin possible de
vous.
5 Relier la pince de masse le plus près possible de la zone de
soudure.
Consignes relatives aux stimulateurs cardiaques :
Les personnes qui portent un stimulateur cardiaque doivent avant tout
consulter leur docteur. Si vous êtes déclaré apte par votre docteur, il est
alors recommandé de respecter les consignes ci–dessus.

3-11. Installing And Threading Welding Wire
. Be sure that outlet cable has proper size
liner for the welding wire size. When
installing gun, position liner extending
from outlet wire guide as close as pos-
sible to drive rolls without touching.
Install gun. Lay gun cable out straight. Cut off
end of wire. Push wire through guides up to
drive rolls; continue to hold wire. Press Jog
button to feed wire out gun.
. For soft wire or small diameter stainless
steel wire, use 2 drive rolls and set drive
roll pressure from 0 to a maximum of 4
on the pressure indicator scale (so that
only the inner spring is compressed).
This setting will generally give the best
performance for these types of wires.
To adjust drive roll pressure, hold nozzle
about 2 in (51 mm) from nonconductive
surface and press gun trigger to feed wire
against surface. Tighten knob so wire does
not slip. Do not overtighten. If contact tip is
completely blocked, wire should slip at the
feeder (see pressure adjustment above).
Cut wire off. Close cover.
Repeat for other side.
Install wire spool. Ad-
just tension nut so
wire is taut when wire
feed stops.
Install wire guide.

3-12. Setting Internal DIP Switches
1 DIP Switch S1
2 DIP Switch S4 (Not For Customer Use)
DIP switch S1 allows the user to make a num-
ber of choices affecting unit operation.
w Selecting Weld Amperage Or Wire Feed
Speed Display (S1-1)
If the front panel DIP is set in the display amps
position, the lower display (see Section 4-6)
shows amperage while the unit is welding at
an amperage value above 25 Amps and the
current detect override is in the Off position. If
the amperage display position is not used, the
lower display shows wire speed.
w Selecting Wire Feed Speed Value (S1-2)
The unit displays wire speed in units of inches
per minute (IPM) if the English/Metric wire
feed display DIP is in the English position. The
unit displays wire speed in meters per minute
(MPM) if the DIP is in the metric position.
w Adjusting Range Limits (S1-3 & 4)
The lock feature provides a means of regulat-
ing unit settings, but still allows some level of
adjustment through the Adjust control. When
a lock position is used, the lock applies to all
programs. Two DIP switches are dedicated to
locking unit settings. Four possible combina-
tions of the two DIP switches provide the fol-
lowing settings: Locks Off, Locks On ±5%,
Locks On ±10%, and finally Locks On ±20%.
If the wire speed is at 300 IPM when the lock
DIP is activated, and the lock range is set at
±10%, the operator would have an adjustment
range from 270 to 330 IPM.
Trigger Hold and Dual Schedule function nor-
mally when locks are enabled.
w Setting Display Hold Feature (S1-5)
If the display hold DIP is in the “Hold On” posi-
tion, the unit will hold the last weld information
for 5 seconds following weld termination. If
any front panel push button is pressed, or if the
Adjust control is activated, the display hold
feature is terminated.
w Setting Current Detect Override (S1-6)
Current detect override is used to disable run-
in when a welding power source is used that
doesn’t provide current feedback through the
14-pin receptacle.
w Defining Motor Speed (S1-7 & 8)
Switches 7 and 8 allow the user to define
whether the motor in use is normal speed
(50–780 inches per minute) or high speed
(90–1440 inches per minute).

1 Upper Display
The upper display shows voltage or time.
The unit displays both preset and actual arc
voltage. When the unit is in a welding state,
actual arc voltage is displayed. The upper
display shows welding sequence time when
the Time LED is illuminated.
2 Upper Display Push Button
Press button to choose between voltage or
time functions.
3 Upper Display Push Button LED
The upper display push button LED illumi-
nates to indicate that information displayed
can be changed by the Adjust control.
4 Volts LED
5 Time LED
The LEDs below the display illuminate to in-
dicate which value is being shown.
At any time while welding, the unit permits
the adjustment of the weld sequence voltage
and overrides the display of actual arc volt-
age. If the current detect override is in the On
position, the unit displays preset voltage
while welding instead of actual arc voltage.
Preset voltage is defined as the desired arc
voltage commanded to the welding power
source.
If the unit is displaying a welding sequence
that can be timed, the welding time display
mode is entered by pressing the upper dis-
play push button repeatedly until welding
time is the active parameter in the upper dis-
play. At idle, the upper display toggles be-
tween showing weld voltage or weld time,
with subsequent presses of the upper dis-
play push button.
The unit defaults to displaying welding volt-
age when a welding sequence display mode
is first entered. When the unit is in a welding
state, the welding time display mode is ter-
minated in place of the voltage display
mode.
If the weld sequence has a time set (as in
spot time), after the weld program is com-
pleted, ERR TRIG will be displayed to indi-
cate the weld program is complete. Release
trigger to clear error.
4-6. Lower Display
1 Lower Display
The lower display shows wire speed or
amperage. The unit displays and adjusts
only preset wire speed at idle. When the unit
is in a welding state, actual wire speed is dis-
played for the active welding sequence. If the
amps display DIP is set in the display amps
position (see Section 3-12), the lower dis-
play shows amperage while the unit is weld-
ing.
2 Lower Display Push Button
Press button to choose between wire speed
or amperage functions.
3 Lower Display Push Button LED
The lower display push button LED illumi-
nates to indicate that information displayed
can be changed by the Adjust control.
4 Wire Speed LED
5 Amps LED
The LEDs below the display illuminate to in-
dicate which value is being shown.
If the unit is in a welding state that does not
involve feeding wire, the unit displays the
weld sequence wire speed. At any time dur-
ing welding, the weld sequence wire speed
can be adjusted and overrides the preset
wire speed display. In other words, if the Ad-
just control is activated while welding, the
unit displays and permits adjustment of the
weld sequence wire feed speed regardless
of the active welding sequence.
When the unit is displaying amperage, the
Amps LED illuminates. Amperage is only
displayed if the unit is in a welding state and
the amperage is above a minimum value of
25 Amps.
The display will read zero for amperage
readings below the amperage threshold,
prior to arc initiation. In addition, the amper-
age display feature is disabled if the current
detect override is in the On position (see
Section 3-12).

The Sequence push button allows the selec-
tion of welding sequences. Five welding se-
quences are available. The default sequence
is the Weld sequence. The Weld sequence is
active on power up, and is indicated when no
welding sequence LEDs are illuminated.
Three welding sequence LEDs are located
above the Sequence push button: Start, Cra-
ter, and Preflow/Postflow. The applicable LED
illuminates to indicate which welding se-
quence is active.
• The LED illuminates to indicate that a weld-
ing sequence display mode other than Weld
is activate. Welding sequences other than
Weld must be set prior to initiating the arc.
When the unit enters a welding state, all se-
quence display modes are terminated and
the weld display mode is activated.
If zero time is programmed for a timed se-
quence except for Weld, that sequence will
be skipped.
• In the weld sequence display mode the Se-
quence push button LED is Off , and all other
sequence LEDs are Off. When the Se-
quence push button is pressed, the Se-
quence push button and the Start LEDs illu-
minate. In this condition, the unit is in the
Start sequence display mode, and Start se-
quence parameters are shown in the dis-
plays.
• When the Sequence push button is pressed
a second time, the Start sequence LED
goes Off and the Crater sequence LED illu-
minates. The Sequence push button LED
remains illuminated. In this condition, the
unit is in the Crater sequence display mode,
and Crater sequence parameters are
shown in the displays.
• When the Sequence push button is pressed
a third time, the Crater sequence LED goes
Off and the Preflow/Postflow sequence
LED illuminates. The Sequence push but-
ton LED remains illuminated. In the Preflow
display mode the upper display shows the
preflow time and the lower display indicates
